We have a large (800,000sf) project that is being constructed primarily using precast floor decks and architectural wall panels. Delivery of these components involves many flatbed trailers using heavy wood dunnage blocks to secure the precast. We made arrangements for this dunnage to be returned to the precasters for future reuse. Can we count it in some way? It doesn't fit the normal definition of a take-back program. However, it is an important part of our modular design approach that contributes to our source reduction strategy for CWM.
